I just hope that Ichika will not give up on being a Lilu. It sounds like she has already given up. It probably will take Maoa to help her out, even though Ichika has doubt about Maoa's ability. Aria seems to be neutral about it, but you do sense that she was hoping Ichika would give it a try, otherwise Aria would not bring up this topic in the first place. This is because Maoa took care of the dead ghost, hence there is still a chance. Ichika does not totally trust Maoa ability though. But if she does try, then she knows Maoa will be there to make sure everything is ok. It is definitely a bet, but she has a better odds than most people.
Ichika is care free. She is a good listener and nothing really bother her. Now that she knows Aria is 4000 years old, she would not be surprised that Aria has an encounter with a Roman Emperor. She just does not freak out about Aria's past. That nonchalant attitude is what Aria likes about her. The final panel is super sweet. They need some private time.
We do not know if all the new lilu has to meet Aria in a Isakei desert. If Ichika decides to be a lilu, then she does not need to worry about meeting Aria, because unless something unusual happens, Aria definitely will let Ichika pass through, after all Ichika is Aria's own girlfriend. Also, twirling eyes do not work on Ichika.
Without being an immortal, Ichika will always be a weak link with her peers. She is the only known person who can administer humane assistance suicide. If Ghika gets the sword, she definitely will kill Aria and make her suffer. Aria betrayed her even though we do not know the story. Needless to say, as Arthur explained, Ghika will conduct mass murders again once she has the sword.
Aria of course would not let Ghika kill her. To be killed by your own progeny (vampiric daughter) is really embarrassing and a taboo.
She's not given up on being a Lilu, she's just given up on being one via drinking a Lilu's blood.
